PENCIL-CASE.

Specification of Letters Patent No. 28,487, dated April 5, 1859.

To all whom it may concern:

Be it known that I, DANIEL A. PEIRGE, of East Greenwich, in the county of Kent, in the State of Rhode Island, have invented a new and useful Improvement in Lead- Pencils; and I do hereby declare that the following is a full and correct description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, the same letters in the different figures denoting like parts.

Figure l is an enlarged view of the pencil. Fig. 2 shows a section of t-he saine through the center lengthwise. Fig. 3 is a representation of the lead holder, or the part that moves the lead in and out.

To construct this pencil, first make the tube A with a slot cut through one side nearly its whole length; upon the lower end of this tube, is placed the bulb B, the lower end of which encircles the upper end of the point C, and is solderedtogether with the point to the tube A. The tube D is placed 0n the tube A only leaving space enough between them to receive the spiral shaped wire, which is soldered to the inside of the tube D, so as to forni an inside screw into which E fits so as to be obliged to traverse from one end of the slot to the other whenever the tube D is turned, as the slot prevents E from turning around with the tube D. v

Inside of the tube A is placed another smaller tube F, for the purpose of holding the lead G, this is more particularly the object of this iinprovement-in this pencil the point does not slide into a case so as to protect the lead when carried in the pocket, so it is made to draw back the lead for that purpose and to accomplish this, the end of the lead Gr is inserted into the tube F,in

the end of which is a screw thread cut with a taper tap, so that the hole is largest at the end, to facilitate the entrance of the lead; and one edge of the junction of the tube is slightly depressed, so as to form a row of teeth on the inside, to cut a screw thread upon the end of the lead, as it is turned into the tube. This gives a very firm hold upon the lead in moving it back and forward and prevents the liability to become loose and broken when carried in the pocket.

J represents a handle made of ivory, wood, or other suitable material, which is cemented to the tube D; Lis a ring soldered to the end of the tube A to keep the tube D on in place.

Of the operation or use of the improvement, it will perhaps only be necessary to say a few words. The pencil is held in the fingers of one hand by the bulb and the handle J is turned by the other until the tube F projects beyond the point C, when by placing the end of the lead in the end of the tube and turning it, it will be screwed in and may be drawn into the point by a reverse motion of the handle.

Having thus described the pencil, what I clain'i as my improvement and desire to secure by Letters Patent is- I claim constructing the end of the tube F with a screw thread, and forming the row of teeth therein, in the manner substantially as described, and for the purposes herein set forth.

In testimony whereof I have hereunto set my hand.

DANIEL A. PEIRCE.
